Interval of measure

In essence, we have expanded the field magnitude in a power series and discarded all terms except the first and second ones. It may be proper to point out that we assume that within the interval of measurements the rate of change of the field ... 

This indicates that to know the measurement random error it is not sufficient to know its magnitude only (confidence interval of measurement error) but also the significance level that facilitates the confidence estimate of the obtained measurements. Using the error mean square as a measurement accuracy property is convenient because that value in a normal distribution is associated with a confidence or confidence coefficient of 0.68 probability. The doubled error mean square 2S has... 

According to the definition [1] the traceability chain is the unbroken chain of comparisons or calibrations from the result of a measurement or the value of a measurement standard to the national or international standards, all having stated uncertainties. The uncertainty of each link in this chain (measuring analytical instrument, reference material or other measurement standard) changes over the course of time. Therefore, the calibration intervals of measuring equipment used in testing (analytical) laboratories [2, 3] and of measurement standards used for their calibration are very important. The same applies to the shelf-life of a certified reference material (CRM) as a measurement standard. So, taking into account these... 

Stability of the traceability chain in chemical analysis is dependent on the calibration intervals of measuring equipment and shelf-life of CRMs used for the calibration of the equipment.

TCDD was absorbed (less than 50% of the applied dose) at each interval of measurement, about 70% of detected radioactivity on the skin could be removed by swabbing with acetone. About 15% of the dose was detected in the liver of rats 24 hours after dermal exposure to 26 ng of 2,3,7,8-TCDD in 50% methanol (Poiger and Schlatter 1980). It was estimated that the amount absorbed from the dermal exposure represents 40% of the amount absorbed from an equivalent oral dose. Absorption of...

F is the averaged photokinetic factor within the time interval of measurement. In eq. (5.130) the thermal rate constant is determined independently. 

For the case where different chemical species in a mixture have different rates of reaction with a reagent, it is possible to treat each species separately. That means that during a certain time interval only one of the species has to be considered because the other species have already reacted or react so slowly that they do not interfere with the rate measurements. The criteria for neglecting reactions of slower or faster reacting components are the ratio of their rate constants, the ratio of their concentrations, and the time interval of measurement. 

The instrumentation for heat o>ndu( vity measumnents as wdl as the method of specimen preparation were essentially the same as in [83] except for a slightly broader temperature interval of measurements (100-300 K) ai the lowor initial pressure (0.1 GPa). 

Faster reactions can be studied by the method of pulse polarography. In this method, the potential, at which the limiting current appears not immediately but some time after the appearance of the droplet, is applied to the electrode. This makes it possible to shorten the current period t for the period of droplet formation and to enlarge the interval of measuring rate constants to 10 ° l/(mol s). 

Interval of measure—This is the range of concentrations on which the dosage can be performed with accuracy and precision. It ranges from the LOQ to the highest concentration of the domain of linearity.
